Would a scattering of your beloved's ashes be good for plant growth? Or could it be toxic? We take this question to Head of Horticulture Sally Petit at Cambridge University's Botanic Gardens.
Fascinating topic, well handled. And yet I'm left pondering - given that too much or little of anything in a plant pot would be detrimental, and that human 'cremains' are 3 to 4 kg / litres, I'm wondering what plant pot volume would be about right for a product that is plant + compost + cremains. For eg, at 5% cremains, the pot would be 60 Litres - indicating more a tree business than pot plant?! Bill Jenks, Mon, 9th Jun 2014
